Fusion's fuel problem — and the breeder-first answer.
D–T fusion needs tritium, which barely exists; D–³He needs helium-3, which is scarcer still. Most of the industry hand-waves the fuel. Kronos breeds it first.
The problem
The fuel nobody wants to talk about.
01
Tritium barely exists
A decaying stockpile on one aging route — and every D–T machine needs it to start.
02
Helium-3 is scarcer
In shortage since 2009, with no primary terrestrial source at scale.
03
Most plans assume it away
Fuel supply is the quiet gap under many fusion roadmaps.
Kronos begins with the fuel: a breeder that makes tritium and helium-3 at home, then a generator that burns it. Fuel follows purpose, not platform.
Verify it yourself
Open by design.
Conceptual design and simulation study; the integrated Kronos machines are not yet built, and certain results are requirement-class. No financial figures are published on this site.
